JOSEPH WALLACE, or NEW YRK, N. Y.

PENCIL.

Application led December 1, 1.921. Serial No. 519,254.

To all 'whom 'it may concern.'

Be it known that I, JOSEPH WALLACE, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Pencils; and I do hereby declare the following to be a full,-

clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to certain new and useful improvements in pencils, and more particularly stated contemplates the production of a pencil of the magazine type in which the lead is advanced or projected from the pencil to form a writingjoi' marking point.

Anobject of my present invention is to provide a pencil of comparatively simple construction, and consisting of but f ew parts which can be inexpensively and easilymanu- 'facturefL Anotheriobject of the'inven ion is to produce a magazine or propelling pencil having a barrel section of novel construction, said section being movably associated with .a tubular end section, and 'arranged to permanently receive the "lead holder, whereby lupon the positive movement of the aforesaid barrel and tubular end sections, the writing lead is projected or retracted `as may be desired. l

A further object of `this invention is to provide cooperating barrel and tubular sections of light weight, the interior and eX- terior portions of which are formed so as to` firmly support the .lead against escape or looseness in writing. j

With these and other objects in view my invention further consists lin the construction and arrangement o f the several parts hereinafter described and pointed out in the appended claims.

In the accompanying drawings in which lhave illustrated two embodiments of my improved pencil,

Figure 1 is 'a side elevation of the pencilg' Figure 2- is a vertical through the pencil;

. Figure is a grpupfigure of the-three parts constituting `my pencil shownseparated and in vertical section; and

Figure 4 is a vertical sectional view through a modified form of pencil.

sectional view The present invention has been primarily .soI

effectivelyv supported against wabbling or f looseness. One section, termed the barrel section for purposes herein, rigidly supports the lead holder, and the other tubular tapered or pointed section serves toguide and support the lead holder and lead. A simple screw thread connection permits of the relative movement of the barrel and tubular sections, one toward the other, thereby providing for the uncovering of the lead writing point when the tubular section is drawn within the barrel. rlhe parts can be easily separated and replaced.

Referring to the drawings in which correspending reference' characters designate similar part-s in the -several views, my im-y proved pencil includes a barrelsection. 1, .i intol which is threaded the tubular tapered or pointed section The material ofwhich these said sections may be made, may be wood, aluminum, brass, or other metal, hard rubber, or composition. I prefer, however,

terior of the barrel is drilled and threaded."

In practice, the opening 4 is drilled to a greater diameter av distance; into the barrel as shown by the numeral' 5. From a point at which this drilling stops to a point substantially midway or intermediate the barrel, the original opening 4 is threaded as shown at 6'.' These internal threads are located at. a point well'inside the barrel.

Internal threads 7 are provided at one end -of the barrel.v for the cap 8, which forms a closure for the ,chamber 9 vadapted to re- -ceive'the extra -leads `as will be understood.

'Q 'Lhelead` holder-L10l consists of a rod 11 preferably of brass or other metal, upon one end of'which is formed the usual split clamp section 12' for gripping and retaining the writing lead, and upon the other end of which is secured a head 13. Any meansof securely attaching the rod 11 to the. head 13 may be employed, rfhe head 13 is cylindrical in shape, and is ,of adiameter which can be forcedor pressed into the opening 4 of the barrel land there snugly retained againstv dislo'dgment. The; material of Y which the'head 13 is made ma be hard rubber or metal, it being desira le'to provide materials which will frictionally adhere and ,in place, lthe holder ispreferably yinserted 'mi-throught@ threaded and @f jthe barreras@ -tivelysmall diameter isvprovidedin the'section 2,' said opening being arranged andi adapted to vslidingly receive the rodll ofthe lead holder, 'and also the lead point 15 carried thereby. The diameter of the open-y -i`ng 14: is reduced at the tapered vend of the section' and is designed to slidingly engage V the Writing lead -to preventfwabbling of the writing point as will be understood.' The inner end ofrthe tubular section 2 55` is threaded asat 16, saidV threaded'p'ortion being'arranged to cooperate with the internally threaded ortion 6 of the barrel 1. The

diameter of t ve. tubular section is reduced as at 17- immediately vadjz'icent the threads 40 116, thereby providing a 'suitable clearance" for the effective.' and smoothl operationo thescrewthreading- The reduced portion 1 stops short how-l ever,' of the end of the barrehthe normal* diameter of the "tubularisection beingfre- `Vstored at this point for sliding engagement- 'I`he` support of theY .tubula s`ect ionj2fat this"l point and as it vpasses within th'ebarrel` l1- when' the lead is luncovered,lis important,

it being. obvious that a vstrong,-dfl';rable,y andf firm construction resu lts. The'-'barrelf 1 is bevelled at this endfandthe mergingor 'ting of the two sections. at this fpoin i 55 ticularly smooth and unobjectionab'l In use, the bf'rrel 1 may' be 4turn l5. for use.

The lead holder 2O is fixed to and carried lby `the section '19." The "extra leadreceiving compa'rtme'nt21isformed in the saidsection 19, and the` cap' 22 serves as a 'clo'sure therefOr-. A

From the foregoing will be seen that I have produced aV compact and simple pencil in'which the-screw threaded connections of the complementary sectionsare entirely con cealed and protected. In practice, I have found this to be of prime importance.

Various changes in the shape, size, proportion and 'arrangement ofthe several parts may be made, and I do not Wish to be understood .as limiting myself tothe exact disclosuresherein, but define my invention as follows. I claim:

1. A pencil of the class described comprising a barrel section formed ,with an opening or bere a portion' of which is internally threaded at a. point intermediate the ends thereof, a 'lead holder rsecured within the aforesaid opening and having a Writing lead adapted to project beyond the barrel, anda tubularsection surrounding said lead' holdery and having an external threaded portion-arranged and'adapted tol 'engage the aforesaid internal thread'sof` the barrelsection, said "tubular section being movable within the barrelfor..uneovering thefwriting lead, and
